Tzedek was founded in December 2012 in response multiple allegations of serious child sexual abuse and subsequent cover-ups within various Jewish community institutions throughout Australia.
Due to rapid development within Australia (including the ongoing Royal Commission into Institutional Responses to Child Sexual Abuse), it was considered most appropriate to establish an independent organisation to respond to this issue.
In 2015, a new CEO, Dr. Michelle Meyer was appointed to the organisation. The organisation has shifted its focus to the prevention of child sexual abuse within the community.
In 2019, Tzedek merged with the South East Centre Against Sexual Assault, which is part of Monash Health, providing a long term future for the organisation. Tzedek continues with its advocacy and support work. It addition, it delivers education and training programs to schools, synagogues and other Jewish organisations. Tzedek also provides support to the Jewish community under the National Redress Scheme.
